    Multi-GPU on Mac with Thunderbolt

    BlackF1re83

      Good morning everyone

       

      I have a MacBook Pro 15" of latest generation (not retina) with Premiere Pro 5.5.2 running under Lion 10.7.4

       

      I have already connected to this Laptop a Promise Pegasus R6, an AJA I/O XT and an Apple Cinema Display 27" all with the thunderbolt daisy chain and works perfectly

       

      I would like to speed up the rendering process adding another GPU to the system using an Nvidia Quadro 4000 MAC installed with a Sonnet Echo Express PRO:

       

      This one:

      Is it possible with my version of premiere or should i upgrade to cs6 to make it work?

      More importantly, can this cfg works?

       

      Thank you very much for your time

            I'm pretty sure that's not going to work for a number of reasons.  First of all: OS X doesn't have drivers in its kernel (or available aftermarket) to address a GPU via the Thunderbolt port.  It's not clear anyone has even considered writing those because of the (lack of) speed of the Thunderbolt ports.

             

            Second is power.  The Quadro needs a 6-pin PCI-E connector from the power supply in order to work properly.  I looked through the technical specifications of that device and didn't note any mention of providing PCI-E power connectors.  And given the power supply, (100W or 150W), it's not clear it even could.

             

            All isn't lost, however.  Assuming you have the right MBP with a 1GB nVidia GPU, you can still enable hardware MPE with the text file edit.  Hunt around for instructions on how to do that edit; you can do it with your existing installation of PPro (and I'd recommend staying there vs 6.0 for the time being).

              Thunderbolt has the equivalent Bandwidth of a PCI-E Gen1 4X slot or Gen 2 2X bandwidth. This is really low for a video card device. I would not recommend it.

                Eric,

                 

                Thank you

                 

                You just educated me, I was all enthused with the new Gigabyte motherboards that have a pair of Thunderbolt interfaces that I was thinking of for external disk drive arrays.

                  Thank you for your answers.

                   

                  I think everything is now clear.

                   

                  I'll keep my system as it is now.

                   

                  Thank you very much
